本文详细解析了Spring MVC中路径映射的工作原理，包括DispatcherServlet如何处理GET请求，RequestMappingHandlerMapping如何查找对应的处理器方法，以及当未找到匹配路径时如何处理等问题。

@Controller
@RequestMapping(value="/api")
public class HelloController {

@Controller
@RequestMapping(value="/api")
public class HelloController {

 

         @RequestMapping("/hello")
         public ModelAndView hello(){
        	 
        	       System.out.print("进来了");

                   ModelAndView mv =new ModelAndView();

                   mv.addObject("spring", "spring mvc");

                   mv.setViewName("hello");

                   return mv;

         }

}

@RequestMapping(value="/api")新增这个注解

然后新增访问路径新增api
